Several NASA photographs, taken by the Curiosity Rover on February 29, 2016 and March 3, 2016 apparently show a strange artificial object peeking from behind a rock formation.

Video uploader Frank Van Asch compared the black and white images taken on February 29 with the color images taken on March 3 and discovered, although the images were taken from different angles, that the strange object only appears in the color images.

The object seems to be a sort of machine or transport vehicle. One part of the object is clearly visible and resembles a sort of rack whereby Frank wonders whether someone else is on Mars who monitors the activities of the Mars Rover.
